Bug#812288: dune-geometry: FTBFS with GCC 6: test suite fails

[Martin Michlmayr]

Package: dune-geometry
Version: 2.4.0-1
Severity: normal
User: debian-gcc at lists.debian.org
Usertags: ftbfs-gcc-6 gcc-6-unknown

This package fails to build with GCC 6.  GCC 6 has not been released
yet, but it's expected that GCC 6 will become the default compiler for
stretch.

Unfortunately, it's not clear from the log why the build failed.
It's possible there's a bug in this package or in GCC.  It's also
possible I reported a non-issue, although I tried to avoid that.
I apologize in advance if this is the case.

If you have some time to look into this issue, that'd be great.  If
not, I can re-test the package with GCC 6 in a few weeks time.

You can find a snapshot of GCC 6 in experimental.  To build with
GCC 6, you can set CC=gcc-6 CXX=g++-6 explicitly.

You may be able to find out more about this issue at
